In adjoining Noida, PM10 pollutants were at 291 while PM2.5 pollutants decreased to 291. According to Center-run SAFAR, Vasundhara and Ghaziabad had an AQI of 196 while Pusa's AQI was 202.

The total number of ministers in the state Cabinet has now gone up to 12, including Chief Minister Manohar Lal Khattar and Deputy Chief Minister Dushyant Chautala.

During winter season each year, most of northern India suffers from a spike in toxicity in the air due to the change in weather patterns and crop residue burning in states of Haryana, Punjab and Uttar Pradesh.

The court took cognizance of the matter after stubble burning in Punjab and Haryana and other meteorological factors pushed Delhi's air quality level down to the 'very poor' category.

This is not the first time the central probe agency has carried out such a massive search operation. It has carried out several similar searches in bank fraud cases in the last few months.

The apex court also summoned chief secretaries of Punjab, Haryana and Uttar Pradesh to appear before it on stubble burning and pollution issue.

Speaking on the situation in the national capital, the court stated the situation was being repeated every year and it is not tolerable.

Principal Secretary to PM had earlier reviewed the situation on October 24. A series of meetings have taken place for the necessary preparation, including one meeting by the Cabinet Secretary on this subject (air pollution), on October 4.

Union Environment and Climate Change Minister Prakash Javadekar had urged Delhi Chief Minister Arvind Kejriwal to take measures to tackle air pollution in national capital instead of indulging in 'blame-game'.

Citing data from the National Aeronautics and Space Administration (NASA), Chautala rapped Delhi Chief Minister Arvind Kejriwal, saying that Punjab is mostly responsible for the air pollution due to stubble burning.
